FOX's GLEE returns for season four tonight, September 13, with an episode titled 'The New Rachel.' Tune in tonight at 9pm to find out what happened to last year's seniors and meet the new crew at McKinley High.

The fourth season of GLEE promises a host of surprises as well as guest appearances by Kate Hudson and Sarah Jessica Parker. The show will also welcome new cast members Dean Guyer, Jacob Artist, Melissa Benoist and Becca Tobin, and will see the debut appearance of GLEE PROJECT season 2 winner Blake Jenner.

GLEE is a musical comedy about a group of ambitious and talented kids who escape the harsh realities of high school by joining a glee club where they find strength, acceptance and ultimately their voice. This year, the senior class is riding high from their Nationals win and enjoying a bit of popularity, while the graduating class leaves the comforts of McKinley for the cruel streets of New York as they open a new chapter and continue chasing their dreams.
